will leakage from valve seal damage turbo?
hi, i have two valve seals leaking on the exhaust side, the oil goes into the exhaust manifold and then into the turbo, will this seeping of oil into turbo through the manifold cause damage to the turbo or seals?

I've seen photographs of turbos containing so much carbon that they could no longer spin. This was attributed to turbo seals leaking. I suppose the same thing could eventually occur if enough oil was fed into the turbo.
Is there a reason why you don't rectify the valve seal problem?

It could build up on exhaust turbine wheel and slow your spool. It could also make wheel off balance and accelerate wear on bearing. Are you topping off your oil weekly? Also, how is your cat and front oxygen sensor working with the extra layers of oil buildup? Have you priced the front oxygen sensor?

A bad valve seal dumps oil directly into the cylinder and then the oil makes it way to the exhaust manifold.

Finish the tune and replace. Watch your boost and AFR after replacing valve stems. If your turbo has buildup, it should slowly burn off and turbo can go back to normal. Hopefully, your tuner accounted for the normally faster spool and higher boost. Make sure your tuner knows what's happening with your engine. Tuning on an unhealthy engine is a bad idea.
